The ‘SMTP error 452’ indicates the email server has reached its capacity. This error can occur when trying to send a large volume of emails or when an email includes an extensive list of recipients.
Essentially, it’s an indicator that the server is running out of the necessary storage or memory.
Resolving the Error – Solution
To resolve this error, start by checking how many emails your email platform allows you to send. If you’re always hitting this limit, you might need to ask your SMTP provider for a higher number.
If you often need to send more emails than most SMTP servers allow, think about using a service like SendLayer. It makes sure your website’s emails get through without problems.
Also, don’t forget to keep an eye on your email logs and your server’s resources. Regular checks on your server’s storage and memory, combined with ensuring your mail queues aren’t overflowing, can help you avoid running into this error again.
That’s it! Now you know the common causes of the 452 error and how to resolve it.
